Les Petites Pierres is a French nonprofit crowdfunding platform focused on helping associations improve access to decent housing and tackle poor housing conditions. It connects donors with community-led projects addressing social exclusion, supporting independence, reducing energy poverty, improving living conditions, and building social ties through housing. Associations can submit projects for review by the platform’s validation committee and run fundraising campaigns, share updates, and reach potential supporters. The platform also offers personalized guidance to participating organizations throughout their campaigns.

A distinctive feature is its commitment to doubling donations, helping projects raise more for initiatives such as renovating shelters, creating inclusive shared housing, supporting families in need, and improving accommodation for vulnerable people. Les Petites Pierres states that the platform is free for associations and charges no commission. Donors can make contributions online and receive a tax receipt; the site indicates that donations may qualify for a 75% tax deduction. Through project listings, campaign resources, donor information, and association support, Les Petites Pierres helps turn charitable giving into practical housing solutions.
